Explain the importance of Thomson’s experimentation with the Cathode Ray Tube.
Summarize his model of the atom.
Thomson’s model changed our view of the atom. Compare and contrast his model to Dalton’s model. What new knowledge did we gain? What was wrong with Dalton’s model? Did any of Dalton’s ideas continue to be valid?
